Title
Deskflow: Local privilege escalation via unauthenticated IPC
Summary
Deskflow is a keyboard and mouse sharing app. In 1.20.0, 1.26.0.134, and earlier, Deskflow daemon runs as SYSTEM and exposes an IPC named pipe with WorldAccessOption enabled. The daemon processes privileged commands without authentication, allowing any local unprivileged user to execute arbitrary commands as SYSTEM. Affects both stable v1.20.0 + and Continuous v1.26.0.134 prerelease.

CVE-2026-41476 (GCVE-0-2026-41476)

Title
Deskflow: clipboard deserialization global-buffer-overflow
Summary
Deskflow is a keyboard and mouse sharing app. Prior to 1.26.0.138, a remote memory-safety vulnerability in Deskflow's clipboard deserialization allows a connected peer to trigger an out-of-bounds read by sending a malformed clipboard update. The issue is in the implementation of src/lib/deskflow/IClipboard.cpp. This is reachable because ClipboardChunk::assemble() in src/lib/deskflow/ClipboardChunk.cpp validates only the outer clipboard transfer size. It does not validate the internal structure of the serialized clipboard blob, so malformed inner lengths reach IClipboard::unmarshall() unchanged. This vulnerability is fixed in 1.26.0.138.
Severity ?
7.4 (High)
